Post-datum: 2024-10-16, Renesas Electronics America

ICL8038CCPD Introduction

The ICL8038CCPD is a versatile waveform generator IC that can produce highly accurate sine, square, triangular, sawtooth, and pulse waveforms with minimal external components. With a frequency range that spans from 0.001 Hz to over 300 kHz, it allows for flexible frequency selection via resistors or capacitors and supports frequency modulation and sweeping with an external voltage. 

The ICL8038 is manufactured using advanced monolithic technology, including Schottky barrier diodes and thin-film resistors, ensuring stable output across a wide temperature range and supply variations. Additionally, the IC can be integrated with phase-locked loop circuitry, which helps reduce temperature drift to under 250 ppm/°C, making it a reliable choice for high-precision signal generation applications.
